"When Yves Perreault looks out over the pristine waters of Desolation Sound, where his family annually harvests half a million oysters, he fears for the future of the ocean – and the industry that supplies Canada with half its shellfish."

"Something is killing oysters and scallops in dramatic numbers, causing suppliers to warn of shortages and producers to worry about the future of their businesses. The cause is unknown, but ocean acidification is the main suspect.

'Its a remote area, the water is clean … we haven’t had any environmental concerns, so I’m not sure what’s going on,' said Mr. Perrault, who owns Little Wing Oysters and is president of the BC Shellfish Grower’s Association."
